H2: What the difference between LDAPv2 and LDAPv3?
There are two versions of LDAP in use today on the Internet.
LDAPv3 was developed in late 1990's to replace LDAPv2. LDAPv3
adds the following features to LDAP:

Supporting both LDAPv2 and LDAPv3 simultaneously can be problematic
and generally should be avoided. As LDAPv3 is more consistenly
implemented and supports all the features of LDAPv2, use of LDAPv3
is highly recommended.
LDAPv2 is considered historical. As deploying both LDAPv2 and
LDAPv3 simultaneously can be quite problematic, LDAPv2 should should
be avoided.

H3: OID Macros
To ease the management and use of OIDs, {{slapd}}(8) supports
{{Object Identifier}} macros. The {{EX:objectIdentifier}} is used
to equate a macro (name) with a OID. The OID may possibly be derived
from a previously defined OID macro. The {{slapd.conf(5)}} syntax
is:
E: objectIdentifier <name> { <oid> | <name>[:<suffix>] }
The following demonstrates definition of a set of OID macros
and their use in defining schema elements:
> objectIdentifier myOID 1.1
> objectIdentifier mySNMP myOrgOID:1
> objectIdentifier myLDAP myOrgOID:2
> objectIdentifier myAttributeType myOrgLDAP:1
> objectIdentifier myObjectClass myOrgLDAP:2
